net/mlx5: fs_core: Make find_closest_ft more generic
As find_closest_ft_recursive is called to find the closest FT, the first parameter of find_closest_ft can be changed from fs_prio to fs_node. Thus this function is extended to find the closest FT for the nodes of any type, not only prios, but also the sub namespaces.
